WILLIAM DIEBEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO FREDERICK BUCKHALTER AND VICTOR C. DRIESBACH.

CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 483,954, dated October 4, 1892.

Application filed August 29, 1889. Serial No. 322,352. (No model.)

.To all whom it may concern,.-

Be it known that I, WILLIAM DIEBEL, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Circular-Knitting Machines, of which the following is a true and exact specification, due reference being had to the drawings which accompany and form part of this specification, and in which similar letters and figures denote similar parts.

My invention relates particularly to the class of knitting-machines upon which seamless goods are manufactured, or such a machine as is well known under the name of the Branson knitter, and is particularly adapted to the purpose of enabling said inachine to operate automatically at those points where only a portion of the needles are in operation-such, for instance, as where the heel or toe of the stocking is to be formed.

Heretofore in knittingmachines it was necessary when the heel was to be formed that a certain number of the needles should be elevated or thrown out of operation by hand--that is, each needle was elevated separately-and as the machine was operated at that point after each movement of the threadcarrier one of the needles was raised by hand, and after half the heel was formed it was necessary to depress the needles one by one. Again, when the toe was to be formed it was necessary to carry on the same operation by hand.

My improvement consists in arranging and combining those needles in the needle-cylinder which are necessary to be elevated and thrown out of action when the heel or toe is to be formed with suitable mechanism (to be hereinafter described) by which they maybe simultaneously elevated by one movementof the hand.

My invention also consists in novel mechanism, adapted to be connected to the camcylinder, which will lift up one of the needles at each movement of the cam-cylinder when forming the heel or toe; and by readjusting said device it will push down a needle at each movement of the cam-cylinder or thread-carrier when the remainder oi' the heel and toe is to be formed.

My invention also consists in a novel arrangement of belts and pulleys and connections with the cam-cylinder, so that the camcylinder and thread-carrier are caused to reciprocate first in one direction and then in the other, thus alternately picking up or depressing, as the case may be, a needle at the extreme end of the travel in each direction.

My invention also consists in a novel adjustment by which the apparatus is automatically stopped when the desired number of needles have been elevated or depressed by the needle-picker. As was before stated, this invention in no way modifies the operation of the machine when it is used for full knitting-that is, when the entire number of the needles are in operation.

In the drawings, Figurel representsa front elevation of the machine with the .needlepicking mechanism thrown out of operation. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation with needle-picking apparatus in operation. Fig. 4 is a sectional plan view on the line a b, Fig. 3. Fig. 5 is a front sectional view of t-he machine. Fig. 6 is a sectional view on the line x, Fig. 3, showing face of pinion o of clutch on shaft 02. Fig. 7 is a section on the line y y, Fig. 3, showing face view of the wheel 7c on shaft 7c. Fig. S is a diagrammatic view showing the loperation of the jaws of the needle-picker when lifting the needles. Fig. 8n is a detached perspective View of the plate d2 and wedge-block d". Fig. 9 is a detail showing the operation of lifting the needles. Fig.-

10 is a detail showing the needle-picking def vice adj usted so that it will force the needle down. showing the operation of the needle-picking device when pushing the needles down. Fig. l2 is a sectional View on the line M M, Fig. 3, looking in the direction of the arrow. Fig. 12X is a detached perspective View of frame X, &c. Fig. 13 shows the needle-elevating cams. Fig. 14 shows the knitting-cams. Fig. 15 isa plan of the cam-cylinder. Fig. 16 is a sectional view on the line R R, Fig. 2.

A represents the cam-cylinder, which is provided with the knitting-cams a c a2.

B B B are the needles, which rest in the needle-cylinder A5, the but-ts of which are in Fig. 1l is a diagrammatic view pacity to slide around said cam-cylinder for a line with the cams a, a a2. When the camcylinder A is revolved by the shaft A', driven by the pulley-wheel k, the thread-carrier A3 is moved by the cam-cylinder upon which it is supported, and the cams d a a2 elevate the needles in order and then depress and again elevate them, the needles following the path b b, and thus forming the loop and stitch. This operation is the ordinary one of knitting and need not be more specifically described.

After the knitting has proceeded for a sufficient distance and it is desired to form the heel of a stocking in the ordinary operation one-half of the needles are elevated byhand,

so as to be thrown out of operation, and then the machine operates as before, and at each reciprocation one fresh needle is elevated or thrown out of operation. My improved mechanism has for its object to perform this operation automatically. The needles rest upon the support B in the cam-cylinder A. Within the cam-cylinder, extending half-way around the same, is the needle-elevating plate B2, provided with the insets B4, engaged by cams B5. The object of making the elevatingplate B2 extend half-way around the cam-cylinder is that when it is operated, as hereinafter described, one-half the needles will be elevated and thrown out of action. The spring-actuated plunger Z, secured to the lifting-plate B2 by the pin z, holds the plate normally down. The cams B5 are connected through the cam-cylinder Awith the sliding bar Bi by the pins bs, said bar being upon the outside of the cam-cylinder and having a cacertain distance, the distance being governed by the extent of the slots b in the cam-cylinder, the pins bs striking the ends of the slots. When this bar is operated in one direction, the needle-elevating cani B2 is brought into the position shown in Fig. 13, thereby elevating one-half of the needles. In operating the machine the cam-cylinder is brought to the position where the thread-carrier is directly in front of the machine, and then this bar B(i is operated, lifting one-half of the needles.

C indicates part of the frame for the needlepicking apparatus or attachment and is supported by the upright rod C12.. Secured upon `this rod is the bracket C', above which is the frame or plate C2, having the notches or detents c c'. The needle-picking apparatus is supported'by the bracket O3, which is a part of the frame or plate C2, journaled on the rod C12, so that the plate and bracket C3 can be swung away from the cam-cylinder or brought into such a position that it can be connected with the cam-cylinder, as will hereinafter be described, so that it can be operated. The plate and bracket are vheld in their different positions by the spring-arm c2, connected to the bracket C', which enters either the detents c or c', dependent upon the position of the attachment. This needle-pickin g attach- Vment consists of the bracket C3, having at its outer end the lower guide C5. An upper guide C5 is supported at the outer end of a bracket carried by the rod G above the frame G. Within these guides is supported a springseated plunger C, provided with the lower spring c6 and the upper spring 0X, these springs being coiled around said plunger, as shown in Fig. 5. The spring o6 is for the purpose of returning the plunger when it is forced down by the cams G2 G2, as hereinafter described, and the spring cX is for the purpose of acting as a cushion or buffer when the plunger is returned. Rgidly secured to the lower end of the plunger is the arm C7, to which is hinged the connecting-arm C8, so as to enable it to be engaged and disengaged with the projecting arm B2. Beneath this connecting-arm and loosely journaled upon thek plunger is the needle-picker D, which consists of two jaws d and CZ and the plat-e cl2. This plate (Z2 rests upon the upper surface of the jaws d d. and has projecting from it the wedge-shaped piece dx, which passes betweenthejaws d d and has its lower end flared out, as shown in Fig. S, which prevents the plate cl2 from being removed from the surface of the jaws, the projection between the jaws being for the purpose of separating the jaws, so that they become inactive, and of allowing the plate to come into action, the jaws being sufciently iiexible to allow the movement of the wedge. When the plate is in the position shown in Fig. 9, the jaws are closed, so

as to form a narrow opening, While when drawn out into the position shown in Figs. l0 and ll the jaws are open and the plate projects at the side of and beyond said jaws. At the upper end and attached to said plunger C6 is the hollow arm E, said arm 'E being oonnected to said plunger CG by the set-bolt e,

vso that it is rigidly attached to said plunger.

cam-rod L,

Within the hollow arm E is the carrying at one end the rollerl and projection Z and at the other end the-thumb-piece e2 and leaf-spring e3, The cam-rod is acted upon by the spring e4, and the rod is held in its inner position by the projection e5 on the leaf-spring e3, which catches the knob e2, and upon releasing this leaf-spring the plunger and knob will move forward until the knob strikes the end of the arrn E, as shown in Fig.

5. Attached to the rod G, which extends from the bracket G3, is the cam-frame G. At-

tached to this frame G" are the spring-seated guides g and g', said guides being springseated rods. They are spring-seated, so as to' give in one movement of the plunger C, and connected to these guides in the interior of this cam-support are the cams G2 and G3. The cams G2 and G3 are supported in springseated guides, so that on the return movement of the plunger C6 said plunger can depress and pass by said cams. Upon the interior of said frame G are the outer'buffers G4 G5 and the intermediate buffer G6. When the plunger C6 is moving in one direction, the roller strikes the under face of the cams, which depresses the plunger, while in its IOO movement in the other direction it strikes the upper face of the cams, forcing the cams down with or in the spring-seated guides g g', allowing the plunger to pass by said cams. In the interior of the frame G are the slots l and 2, through which pass the pins 3 3 and 4: Ll, (two for each ca1n,) said pins being fastened to the guide-rods 5 5 and 6 6.

A is the main shaft of the machine. Connected with this shaft are threepulleys or wheels lo lo k2, which normally run idle'upon the shaft A. Connected with the pulley lc is the belt 7e3 from the source of power. Connected with the pulley 7a2 is a cross-belt 7a4, connected, also, with the source of power. When the machine is Aoperating in the ordinary manner--that is, when the needle-cylinder is being revolved in one direction onlythe shaft A is thrown into gear with the driving-pulley 7c by means of the clutch member M, which is operated by the hand-lever M. This clutch member is operated by the forked rod M2, the collar of the clutch resting in the forks of the rod. Connected to the forked rod M2 is the spring-actuated rod M3, which is in turn connected to hand-lever M by toggle-joint mechanism. The forked rod M2 forces the projections fm" and ym2 in the clutch member into the orifices m2 in the pulley. The pulley then rotates the shaft through the medium of the clutch member.

When it is desired to operate the needle picker or depressor, the operation is as follows: The cam-cylinder is rotated until the thread-carrier A2 is at the front of the machine. The needle-picking mechanism is then swung to the front of the machine and the arm C7 is connected with the projecting arm B9 on the cam-cylinder, and the needle-picker is brought to the front of the machine. The elevating-rod BG is then operated and one-half the needles elevated and thrown out of operation. The Aneedle-picker is brought into the position shown in Figs. S and 9, and the camcylinder is caused to reciprocate in the following manner: The pulley 7c has a sleeve O upon the shaft A', which has at its end the gear o, which gears into the wheel o', which runs loosely 011 the shaft o2. On the other end of this shaft is the gear-wheel o3, which gears in the wheel o4 on the main driving-shaft. Connected to the end of thel main driving-shaft is the bevel-gear 05, which works in the gear o6 on the cam-cylinder. On the shaft o2 is the clutch member o2, which is brought into engagement with the gear-wheel 0 by means of the spring-actuated arm 03, which has the end bifurcated and embracing the clutch member. This clutch member is normally held out of engagement with the wheel o by means of the spring-actuated plunger 02, which has the arm 010, resting against the arm and holding the clutch member out of engagement. Vhen the plunger o is released byv means of the operator pressing on the part 012, pulling the stop 013 out of connection with the plunger, the plunger rises, which releases -the arm o8, and it is moved forward by the spring 020, one end of which is secured to the arm o8, the other to the bracket 020, pushing the clutch o7 forward, and the projections 014, &c., of the clutch member enter the orifices o15 in the gear-wheel o. The ends of the arm o8 travel in a slot o19 in the projection from the clutch member, and the lever 08 and the plunger o9 and its mechanism are carried upon the bracket 020. Projecting from the plunger o9 is the arm 015, having the projecting lug o16. This projecting lug 016 when the clutch is in operation is in the line of travel ofthe prol jection o upon the cam-cylinder, but is out of the line when the clutch is out of action. Connected to the bracket 020, upon which the clutch-actuating mechanism is mounted upon the shaft o2, is the plate P, which plate has an arm p connected to it, and upon said arm is pivoted the pawl p', which works in the toothed wheel p2, which is journaled upon the projection p2 from the main frame of the machine. On the other end of the plate -P is the arm p4, having connected to it the bent rod p5, which bent rod rests at or near its outer end between two dogs p6 and p7, and the rod p5 is so bent, as shown, that in its movement it will cause the dogs to travellongitudinally, said dogs being connected to the plunger p2, supported in the sleeve'pso, secured to the frame of the machine. At the outer end of the plunger p2 is the belt-shifting arm p9,

which projects to the back of the machine and has a bifurcated end 1010 p11. Also connected to this plunger is the beltshifting arm p12,

which projects to the front of the machine and has the bifurcated end p13 p14. When the plate P is vibrated, it causes the plunger to` travel forward and backward and the two arms, with their bifurcated ends, follow the plunger. These arms are in connection with the belts, so that the belts which normally run on the pulleys 7c k2 are shifted by the movement of the plate and forced alternatelyupon the pulley 7c', the arm p12 shiftingfthe: belt k2, which normally runs on the pulley 76,'

while the arm p9 shifts the belt 7a4, which n ormally runs on the pulley Now the operation being to form the heel of the stocking,

the needle-picker slide d2 is brought into the' position shown in Figs. 8 and 9, the 11eedlepicking mechanism being connected to the projection Bfon the cam-cylinder. The springactuated arm o8 is then operated and the clutch member 07 thrown into connection with the gear-Wheel o', which Will cause the pulley 7c to revolve the cam-cylinder by the intermediate mechanism before described, and the arm Q is pushed down or up, which through the medium of the arms heretofore spoken of shifts one of the belts from the idle-pulleys 7o 7a2 onto the active pulley 7c. This causes the pulley 7c', to revolve and it revolves with it the cam-cylinder. The cylinder is caused to revolve first in one direction and then in the other` by means of the lug o17 on the camcylinder striking the projecting lug 016, con- IOO IIO

nected with the plunger o2,y which causes the bracket o20 to rock and with it the rod p5, thus actuating plunger p2, which through the shifting-arms p9 and p12 shifts the belts, according, to which side of the lug on the rocking frame is struck by the lug on the cam-cylinder, thus shifting alternately the straight and cross belt onto the active pulley, causing said pulley to rotate, and through the intermediate connecting mechanism, the cam-cylinder first in one direction and then in the other.

Referring to Figs. 8 and 9, and supposing that the lever Q be operated so that thevcamcylinder is caused to revolve initially from left to right, the plunger C6 of the needlepicking mechanism, being connected to the cam cylinder by means hereinbefore described, is caused to rotate with said cylinder, and the needle-picker D is stopped in its lnovement by striking the first needle which is left up, while the plunger CG continues its rotary movement' until the roller Z at the end of the cam-rod L passes under the cam G2, which causes the plunger to be depressed. This depression of the plunger C6 causes the needle-picking jaws CZ cZ2 to descend a distance sufficient to grasp the first needle which is down, at which time the roller Z will have reached the end of the cam G2 and the roller Vwill slide beyond the end of the cam and the lower spring in the plunger will cause it to rise to the buffer GG, lifting with it the needlepicker D and elevating the needle between the jaws. At this point the projection o17 on the cam-cylinder strikes the projection o16 on the plunger o, shifting the belts as hereinbefore described, which causes the reverse belt to rest upon the active pulley, while the other belt is shifted off of said pulley. This causes the cam-cylinder to rotate in the opposite direction, which causes the roller Z to travel upon the upper surface of the cam G2, lifting the plunger and with it the needle-picker free from the needle, the cam G2 yielding in the movement on account 0f the spring-seated frame g. When the pulley slides off the upper end of the ca-m it strikes the buffer G5, which prevents the plunger dropping too far or any shock. The cylinder continues its rotation in the same direction until the roller Z strikes the other cam G2, where the operation is repeated, the plunger being caused to descend until the jaws of the needle-picker grasp the needle, when the roller passes off of the cam, at which time the projection 017 on the camcylinder strikes the lug o16 on the plunger 02, reversing the belts, causing the cylinder to revolve in the other direction and the roller riding up on the top of the cam G3 and releasing the needle from the jaws. The mechanism by which the number of needles elevated by this apparatus or device, which is generally two-thirds of the number of needles elevated by the rod BG, is limited, as follows:

The pawl p', as heretofore described, Works in the toothed wheel p2, and each time the projection'on the cam-cylinder strikes the proj ection on the plunger, Vas described, the bracket 020, to which the pawl is connected, is caused to vibrate, and this causes the vpawl alternately to push the wheel p2 forward one tooth and to be released from it and carried back to the next tooth, the wheel being prevented from rotatingin the opposite direction when the pawl is released by reason of the spring px, which is secured to the back of the ratchet-wheel so as to press upon the shaft of said wheel, as shown in Fig. 12X. The number of. teeth in the wheel 'p2 depends on the number of needles in operation. X is a frame on the back of said wheel p2.

p50 are springs, one end of said springs being secured to the wheel p2, the other end of said springs to the frame X, as shown in Fig. l2, thus making the frame X a spring-seated frame. On the back of this wheelp2 is the lug X, said frame sliding between the wheel p2 and collar X10. At the end of the arm p, which is connected to the bracket 020, is the connecting-pin q. The arm p rocks Whenthe bracket 020 is rocked by the projection 017, striking the lug o16 on the plunger 09, thus turning the wheel p2 until the lug X is in the path of movement of the armp, when the pin q strikes it on its downward movement,

depressing the frame X. When the cam-cylinder starts to reverse, the frame lifts the rocking frame up a distance sufficient to bring it to a central position, and the belts k3 and h4 are transferred to the idle-pulleys Zo k2, and the machine is stopped until the lever 'Q is operated to move the wheel p2 forward and the lug X out of rconnection with the pin q, which shifts one of the belts upon the active pulley Zt.

When the number of needles have been thrown out of action, as hereinbefore described, the remainder of the heel is formed as follows: The needle-slide cZ2 is pulled out, Figs. l0 and 1l, opening the jaws OZ and CZ', bringing the'projecting plate Z2 on each side of the frame forward, The cam-rod L is also pulled in, which brings the roller Z at the end of said rod in its movement out of the line of the cams G2 G2. Upon the cani-rod L is the lug Z', which when said rod is brought into the position just described is brought in line wit-l1 the pear-shaped cam W, which is secured to the upper guide C5 of the machine. The lever Q is then operated to move the lug X out of connection with the pin q, shifting one of the belts upon the active pulley, and the machine continues to operate, as before described, first to the right and then to the left, the needle-picker striking the first needle that is up, and when the lug Z strikes the cam W it is forced down, forcing the plunger (3fi down, which pushes the slide Z2 with it, forcing the needle down until the lug Z has reached the lowermost portion of the cam, when the lug o17 on the cam-cylinder strikes the projection on the plunger o", causing the machine to reverse, and the same operation is carried on With the needle on the opposite TOO IIO

side of the needle-cylinder. The duration of this operation is limited in the same manner as was hereinbefore described in reference to limiting the number'of needles to be thrown 'out of action in the formation of the heel.

` 'jecting shanks of the needles B,forcing them down into their normal position and in the path of the cams a c a2. This plunger R is held down by means of the leaf-spring fr', which has the projection r2, which rests in the 'detent r2 in the plunger when the plunger is down. When this plunger R reaches the point where the projection T is on the frame of the machine, said projection being in the path of the spring 0^', said projection T strikes the lower end of the leaf-spring fr', forcing the projection p2 out of engagement with the detent r2, and the plunger R, by the spring r2, against which the plunger is forced down, forces the plunger up, carrying with it the depressor S, which is prevented from rising too far by the overhanging lip t3 on the leafspring, the projection T being in such position on the frame of the machine that it is opposite to the needles elevated by the plate B2 and is in front of the needles not acted upon by said plate B2.

In forming the toe the operation is the same as that described for the heel.

The operation of the entire machine is as follows: In making lirst the leg of the stocking the automatic needle-picking mechanism is thrown out of action, as shown in Figs. 1 and 2. The clutch member M is operated, which throws the shaft A into connection with the pulley lo, causing the straight belt, which normally rests on said pulley, to rotate the shaft and through the medium of the bevel-gear o5 the cam-cylinder, carrying with it the thread-carrier, the cams'within the cylinder causing the needles to be alternately elevated and depressed, making the looped stitch by means of the butts of the needlespassing through the cams, as heretofore described. This continues until sufficient of the leg has been formed. Vhen the heel portion is reached, the needlepicking mechanism is shifted to the front of the machine, as heretofore described, the clutch-member which brought the idle pulley k into connection with the shaft A is released, and the needle-picking mechanism is connected to the cam-cylinder, as hereinbefore described. The camcylinder is then revolved until the threadcarrier is in front of the machine, when the lifting-rod B6 is operated, which elevates throughv the medium of the lifting-cams B5 B8,

as heretofore described, half of the needles, throwing them out of the action of the cams Ia ca2. These needles are held up bymeans of the usual spring 3, which surrounds the entire number of needles in the cylinder and rests against their butts. The cam-rod L 1s brought into the position which throws the rollerZ of said rod in the path of the cams G2 G3. The clutch member o7 is thenconnected with the gear o', which causes the shaft 02 to be connected with the gear-Wheel o', and by shifting the lever Q one of the belts is thrown upon the pulley le', which is in connection with the gear-wheel o. The cam-cylinder is then rotated irst in one direction until the jaws of the needle-picker strike and elevate one of the needles. The lug o17 on the cam-cylinder then strikes the lug on thel plunger o9, shifting the reverse belt onto the active pulley lo and causing the cam-cylinder to revolve in the opposite direction, in which direction itrevolves until the needle on the opposite side of the needle-cylinder has been elevated by the needle-picker.' This operation continues until two-thirds of the needles have been picked up, when the machine is stopped, as before described. The cam-rod L is then pulled in so that the roller Z will not be in the line of travel in such position that it will strike the cams G2 G2. The

vneedle-slide is also pulled out so that the jaws d d are open, plate d2 is brought in position. started in the same manner as before described, the only difference being that in place of the needle-picking device elevating the needles they are forced down alternately on each side of the cylinder, and this continues until the proper number of needles is depressed, which is automatically determined, as before described. The picking mechanism is then moved out of connection with the thread-carrier, and the needles remaining up are depressed into the path of the cams, as before described, and the foot is formed in the same manner as the leg. The toe portion is formed in the same manner as the heel.

By my improvement I am thus enabled to automatically knit the entire stocking without it being necessary to elevate the needles and the projecting vby hand or govern the rotation of the needlecylinder.
